Today the Boston Globe published an article claiming that Dzhokhar Tsarnaev made an incriminating statement within earshot of an FBI agent, during a visit with his sisters.
Then we have the odd situation, where a friend of the elder Tsarnev is killed by an FBI agent, when they went to Florida to question him about his complicity in a long unsolved murder in MA, that was linked to the elder Tsarnev (and maybe the younger).
I am not suggesting CT here, but the FBI had the elder Tsarnev on the radar, but they failed in the follow-up.
And the FBI failed in the follow-up to 9/11--not all of them, as FBI whistleblowers stood up.Colleen Rowley, etc.
I am not doubtful of the Tsarnev's complicity in the bombings. But it is strange that the younger Tsarnev is charged with (the phrase drilled in our heads) using "weapons of mass destruction" and the Aurora shooter, and Adam Lanza, are merely mass murderers, though their killings were numerically greater.
This phenomena is not restricted to these terrible killings. It seems, at every step, there are people trying to speak the truth, and others think it wiser to preserve institutional respect.
